HL-LHC BPM System Development Status
/ Krupa, Michal (CERN) ; Bett, Douglas (U. Oxford (main)) ; Degl'Innocenti, Irene (CERN) ; Gudkov, Dmitry (CERN) ; Schneider, Gerhard (CERN)
The demanding instrumentation requirements of the future High Luminosity LHC (HL-LHC) require 44 newly designed Beam Position Monitors (BPM) to be installed around the ATLAS and CMS experiments in 2026-2028. Three BPM types are now in pre-series production, with two more variants under design. [...]

A novel generation of fast Beam Wire Scanners (BWS), developed in the framework of the LHC Injectors Upgrade (LIU), has been recently deployed in the 3 LHC injector synchrotrons, accelerating protons from 160 MeV to 450 GeV, during the 2019-2020 LHC long shutdown. The monitors feature high precision motor controller, high resolution wire position monitoring and wide dynamic range secondary particles detectors. [...]

Metal 3D Additive Machining for in-Vacuum Beam Instrumentation
/ Veness, Raymond (CERN) ; Andreazza, William (CERN) ; Gudkov, Dmitry (CERN) ; Miarnau Marin, Ana (CERN) ; Samuelsson, Sebastian (CERN)
3D additive machining by selective laser melting (SLM) has great potential for widespread use in the field of accelerator instrumentation. However, as with any new process or material, it must be adapted and qualified for use in the specific in-vacuum accelerator environment. [...]
